Nilfisk was founded in Denmark in 1906 as Fisker & Nielsen. Originally the company produced electrical engines as the basic component in ventilators, kitchen elevators, drilling machines and, later on, the Nimbus motorcycle. The Nilfisk vacuum cleaner of 1910, weighed 17.5 kilos. Fisker took out a patent on this invention and later bought out Nielsen. The vacuum cleaner outsold the other products, and the other engine products were gradually phased out. Nowadays Nilfisk produce top-quality vacuum cleaners and pressure washers.
